Patent CA-2324832-A1 (CA)
Inventor: LECOMTE ROGER
IPC: G06F17/12
Filed: 2000-10-31
Abstract: The present invention discloses a method and a system for real-time reconstruction of tomographic images from projection data-generated by computed tomography scanners. The method is based on the theory of pseudo-inverse matrices applied to tomographic image reconstruction, and it allows immediate, projection-by-projection or event-by-event updating of the reconstructed tomographic image at the moment the measuring instrument supplies additional individual projection data. The data processing involves simple arithmetic, which can be implemented into general-purpose computers in the first case, and dedicated programmable logic or application specific circuits in the second case. Models of the underlying physical processes, such as the photon emission and detection processes or the spatially variant system response, can be easily included into image reconstruction through the system matrix. Corrections for other physical and instrumental factors affecting the accuracy of projection data, such as attenuation in the body or detector efficiency normalization, can be merged with the system matrix beforehand or be performed "on the fly" by simple multiplication of the matrix elements.  Real-time updating of the reconstructed tomographic image can be performed as soon as measured projection data become available. No storage of the measured raw data in the form of list mode events or sinogram is required, and the user of the tomographic system may choose to store reconstructed images only, thus achieving optimum compression of the tomographic data.

Patent CA-2333036-A1 (CA)
Inventor: PLATZKER DANIEL M
IPC: G06F3/042
Filed: 1999-10-02
Abstract: This application discloses an apparatus and method of processing images, hand-drawn or written on a suitable Writing Surface (21A, 21B, 21C), viewed by an Image Sensor (22A, 22B, 22C) such as a video camera, and captured by an image sensing circuit (i.e. frame grabber or similar) used for acquistion of image frames by a computer. More particularly, this invention discriminates among changes detected in these Viewed Imges in order to identify and disregard non-informational, transient and/or redundant content. Removal of such content, a writer's arm for example, from the captured image facilitates isolating meaningful changes, specifically intentional new Writing and Erasures appearing on the Writing Surface. Preserving only meaningful changes on the surface promotes optimized compressed transmission of a subset of the visual data, when used in conjunction with digital computer display systems.

Abstract: Low plasma levels of high-density lipoprotein (HDL) cholesterol have been associated with an increased risk of coronary heart disease (CHD). HDL are very heterogeneous with respect to size and apolipoprotein content and the objective of the present study was to develop a method to generate lipid-stainable standards that would allow for the assessment of HDL particle size from whole plasma using polyacrylamide gradient gel electrophoresis (PAGGE). Lipid-stainable plasma standards were obtained by subjecting isolated red blood cells to hemolysis by either freezing at -20°C or -80°C overnight or to rapid exposure to liquid nitrogen and mixing the hemolysis products with plasma aliquots. All three methods were highly reproducible in producing Sudan black lipid-stainable standards ranging from 75 .ANG. to 200 .ANG.. With the use of these standard bands, HDL particle size was assessed with intra and inter assay coefficients of variation below 0.8% and 1.2% respectively. This use of lipid-stainable HDL standards simplifies the assessment of HDL particle size by PAGGE using whole plasma, without having to go through cost and time consuming; ultracentrifugation procedures.

Title: Switching system with mems modification of a signal wavefront
Inventor: RESSL MICHAEL G
IPC: H04B10/27
Filed: 2001-10-02
Abstract: The switching system with MEMS modification of a signal wavefront implements a new type of all-optical signal switching element that uses the coherence properties of electromagnetic radiation, coupled with the materials properties of semiconductors through the application of existing Micro-machined Electro-Mechanical System (MEMS) technology to provide signal switching apparatus that is faster in operation, smaller in size, more robust, and less expensive than existing signal switching elements found in all-optical communication switching systems. This is accomplished by the use of a semiconductor chip that has a MEMS mirror system implemented on its face.  The MEMS device is constructed to operate in a pure materials flex mode, with no moving mechanical parts to wear. The MEMS mirror system is used to create local distortions in the reflected and/or transmitted electromagnetic radiation wavefront to redirect the electromagnetic radiation in such a way as to create channels of changed resistance in a bulk semiconductor. These changes in resistance to the channels serve to enhance or impede the motility of electrons through the bulk semiconductor, thereby providing a switching function within the bulk semiconductor. Alternatively, the redirection of the electromagnetic radiation wavefront can be effected via changes in the index of refraction in the bulk semiconductor material.
